# For those of us who like BBEdit, often a
# command-line flag or variant is used in
# $EDITOR which doesn't return until the file
# is closed.  This is great for things like
# crontab, but not so good when we want to just
# open the file in the editor.  So, if the
# environment variable EDITOR_NOWAIT is defined,
# use it, otherwise use EDITOR.
